CASE STUDIES
Typical modernization situations. Clearly structured.
The following scenarios illustrate how DÜCHTING.SYSTEMS approaches established business software. Specific client information remains confidential.
CASE 01 · REPRESENTATIVE SCENARIO
VB6 · SQL SERVER · OPERATIONS
Modernize a business-critical VB6 application without disrupting operations
Starting point
A long-established Windows application, central business logic, few key knowledge holders and extensive custom functionality.
Approach
Technical assessment, source-code protection, pilot module, clear interface boundaries and incremental migration alongside the existing system.
Target state
A maintainable .NET foundation, documented business logic, reproducible builds and a controlled transition without a risky big bang.

CASE 02 · REPRESENTATIVE SCENARIO
SQL SERVER · PERFORMANCE · STABILITY
Stabilize a slow database and unclear dependencies
Starting point
Historically evolved tables, complex queries, missing indexes and operational uncertainty around changes.
Approach
Workload analysis, data-model review, bottleneck measurement, controlled optimization and documented rollback.
Target state
Measurably faster core processes, reduced operational risk and transparent technical responsibilities.

CASE 03 · REPRESENTATIVE SCENARIO
KNOWLEDGE · SUCCESSION · OPERATIONS
Secure software knowledge before a key developer leaves
Starting point
Much of the technical and business knowledge resides with one experienced individual.
Approach
System map, build documentation, architecture decisions, operational knowledge and structured handover sessions.
Target state
Distributed knowledge, reliable documentation and a system no longer dependent on a single person.
